This is astroneer. Astroneer is all about space and yet we dont have any contact with space except when launching to other planets
Here is my idea: space station
New printed item: Space habitat.
A building module for space
windows and other building features.
engines
ZERO GRAV

When you have a module on the front of a ground vehicle(either Rover or Truck) and a module on the front of a station, when they get near each other they will auto snap off.
Reproduction:
Build a station(any).
Snap a Generator module to the front power outlet.
Build a Rover.
Snap a Generator module to the front/rear power outlet of the Rover.
Drive the Rover near the front of the station until you can see the blue hologram conveyor line.
Results:
Both modules will snap off from the hologram popping up. This also happens when you have 2 ground vehicles connected and you have an object in your hand that can snap to the front/back of a vehicle, it will auto disconnect the line between the vehicles.
Solution(s):
Please fix!

I like the tutorial you have at the start, its good to keep tutorials short but I would walk a player though building their first station. I expanded 4 platforms out before I figured out that I was suppose to pull resin off my back and turn them into stations XD.
Not a huge deal but it would help.
